Abstract: Disclosed is a device for the automatic removal of rejected eggs from an incubation tray, whereby the device includes a suction power above the egg to suck up the egg, and the device further includes a blowing power against the bottom of the egg to blow away the egg, whereby the blowing power blows an air flow or overpressure against the bottom of the egg. Also disclosed is a method for the automatic removal of one or more rejected eggs from an incubation tray.
Abstract: Disclosed is a device for contactless measuring of an embryo's heart rate in an egg whereby infrared light is sent in the egg by one light source, and the reflection of that light is detected by one or more light sensors and converted into a signal representative for the heart rate, whereby a shield is provided to avoid light that is reflected on the egg shell interfering with the light sensors. The shield is provided at the light source and not at the light sensors, whereby a light tube is provided between the light source and the egg and the light tube is internally dimensioned and positioned such that a focused light spot is directed on the egg, and the light tube is dimensioned and positioned such that light reflected on the surface of the egg on the level of the light spot cannot directly reach the light sensors.
